timedrop

Timedrop is a microservice that serves up JSON data containing locations and time zone information through a HTTP rest point.

PREREQUISITES

• nginx is required to be installed if using the RPM package.
• docker (podman) is required if using the CONTAINER image locally.
• kubernetes is required if you wanted to use the .yaml files.

INSTALLATION

There are two ways this package is installed:

1. RPM

yum install -y timedrop-1.1.4-1.el7.x86_64.rpm

The application runs as a systemd service and listens on localhost:9987.

To be externally accesible, nginx must be installed and is accessible through http://ip-address/time

2. CONTAINER

Docker (podman)

I. docker pull ghcr.io/erock530/timedrop:1.1.4

II. podman images | grep timedrop

III. podman run -d -p 8080:9987 --name timedrop-svc POD_ID_FROM_PREVIOUS_COMMAND

The pod can be accessed via curl http://localhost:8080

Kubernetes

Edit kubernetes/service.yml file and make sure an external IP address is configured for externalIPs.

I. kubectl create namespace timedrop

II. kubectl create -f kubernetes/deployment.yml -n timedrop

III. kubectl create -f kubernetes/service.yml -n timedrop

You can verify the service is configured:

kubectl get services -n timedrop

The pod can be accessed via curl http://IP

TROUBLESHOOTING

Not working correctly? Check the pod logs:

Docker (podman):

I. podman container list | grep timedrop

II. podman container logs POD_ID_FROM_PREVIOUS_COMMAND

Kubernetes:

I. kubectl get pods -n timedrop

II. kubectl logs A_POD_ID_FROM_PREVIOUS_COMMAND -n timedrop
